Application

This unit describes the skills and knowledge required to design and specify appropriate testing and commissioning procedures while under industrial conditions in the field for polyethylene (commonly referred to as PE) plastic non-pressure drainage pipelines and vent installations.

This unit applies to an experienced technician working alone or as part of a team.

This unit principally refers to an industry-recognised and specialised skill set for the design of polyethylene plastic non-pressure pipeline systems in the field.

No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.

What You'll Learn

1. Assess suitability of polyethylene pipe materials for specific non-pressure drainage applications

  • 1.1 Identify materials as grades of polyethylene from national standards, job specifications and worksite instructions
  • 1.2 Determine polyethylene materials properties from national standards and material data sheets
  • 1.3 Identify job needs from worksite instructions and job specifications

2. Determine appropriate products from national standards

  • 2.1 Identify material options from national standards, supplier data sheets, and government codes and regulations
  • 2.2 Identify performance limitations of material options from materials knowledge and data sheets
  • 2.3 Identify pipe and component options from national standards, supplier data sheets, and government codes and regulations
  • 2.4 Identify performance limitations of pipe and component options from materials knowledge and data sheets
  • 2.5 Identify suitable jointing methods for pipes and fittings from jointing knowledge
  • 2.6 Identify operational conditions from job specifications and workplace procedures

3. Determine pipeline requirements

  • 3.1 Identify length of pipe required from job specifications
  • 3.2 Identify type and number of fittings required from job specifications
  • 3.3 Select pipe and components in context of specific job needs and product properties
  • 3.4 Identify jointing equipment or materials from job specifications
  • 3.5 Prepare field operational sheets according to workplace procedures
  • 3.6 Adjust design to meet requirements and quality standards

4. Determine testing and commissioning procedures

  • 4.1 Determine specific installation test requirements from job specifications and quality standards
  • 4.2 Establish procedures for commissioning of work to be done from job specifications
  • 4.3 Accurately maintain records and logbooks
